Bad quality of jewelry!!!

I am really done with American Swiss. Whatever jewellery I have purchased there has never lasted and not due to negligence but due to their quality. My husband purchased a 9ct Gold chain for me there in April 2012 on my Foschini account the chain then just loosened by the link I then claimed insurance in October 2013 and the chain was replaced. Last night whilst taking my chain off the chain broke where you would hook the chain into the loop. This is a year later and please note this chain cost R1 499.00. Prior to this I had problems with wedding bands which me and my husband had also purchased at American Swiss. The sales consultant had not advised us that the rings were gold plated and not 9ct gold. All of this has left a sour taste in my mouth. I would like to know whether my chain is still insured or not. Please make contact with me.
